Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

Insuring the safety and control of littoral waters is problematic because of the difficulties of surveillance. The preferred methods of surveillance in the ocean are acoustic. In littoral waters, acoustic methods fail because noise from the surf and reflections from the shallow bottom convolute acoustic signatures beyond our capacity to discern them. Water absorbs light, reducing the effectiven ...

During the Phase 1 effort Streamline Automation demonstrated that the use of a bushing assembly, when paired with the appropriate flexible shaft coupling, could significantly reduce the loads on the shaft of Angular Displacement Transducers (ADTs). These ADTs are currently used as position indicators for quarter turn valves in the ASTF at AEDC. The ADTs are subjected to high vibrational loads du ...

The overall objective of this effort is to design, develop and demonstrate an integrated “Virtual Numerical Laboratory” for evaluation of biological agent defeat strategies. The simulation framework will integrate a novel, stochastic description of agent-neutralizer interactions/distribution with an incompressible CFD code with advanced turbulence, moving body and free surface models. In Phas ...

Explosive devices are the preferred weapon in the majority of terrorist attacks and cause of major injuries to soldiers and civilians. Military medics and future first responders must be educated in the unique blast injury pathophysiology to make decisions in diagnosis, resuscitation, and treatment planning. The objective of this project is to develop high fidelity, multiscale, physiology-based mo ...

Phase I research successfully: 1) demonstrated a prototype fiber-optic coupled laser initiator, 2) analytically and experimentally characterized a single element GOx/CH4 laser ignition process and 3) assessed commercial grade optics/windows, including structural/thermal evaluation of an in-chamber window installation assembly. Phase II will focus on replacing existing squib ignition technology cul ...

Fuel injectors play a vital role in the performance of high performance gas turbine combustion systems. However, current combustion CFD codes cannot accurately predict spray/atomization and turbulent-combustion processes. In this SBIR project, CFD Research Corporation (CFDRC) proposes to develop and validate a CFD fuel injector design tool that will accurately predict spray-combustion in gas turbi ...

The project objective is to develop an integrated software environment for hierarchical prototyping/analysis of hardware for DNA computers and DNA self-assembly. Emerging interdisciplinary field of biomolecular computing explores new paradigms to perform calculations and to design computing architectures at the molecular level. The use of biomaterials in the fabrication and operation of high perfo ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...
